WIRE FABRIC.

., Specification of Letters Patent. P t t d Mar. 2 1

Application filed July 28, 1917, Serial R'o. 182,269. Renewed October 1920. Serial No. 416,296.

T 0 all whom it may concern Be it known that I, WILBER J. PINE, a citizen of the United States, residing at K enosha, county of Kenosha, and State of Wisconsin, have invented new and useful Inprovements in Wire Fabrics, of which the following is a specification.

My present invention relates to new and useful improvements in wire fabrics of a resilient nature adapted for use in connection with spring mattresses, and more particularly of that type set forth in my copending application, Serial No. 182,268, filed July 23, 1917.

It is the object of this invention to provide a fabric composed of units of an exceedingly simple nature, connected to aiford, as in my co-pending application, longitudinal lines of support afl'ording maximum strength and permitting resilient yielding movements of the various units to properly distribute load stress throughout the fabric and thus avoid undesired general sagging.

A more detailed object is to provide a fabric of this nature wherein a plurality of connecting eye-loops are provided to afford a maximum resiliency in connection therewith.

With the above and other objects and ad vantages in view, the invention resides more particularly in the novel combination, formation and arrangement of parts here1nafter described and pointed out in the appended claims.

In the drawings:

Figure 1 is a plan view of a section of wire fabric constructed in accordance with my invention. I

Fig. 2 is a sectional view through the fabric on the line 22 of Fig. 1.

Referring now more particularly to the accompanying drawings, my improved fabric comprises a plurality of series of longitudinal units, the units of each series being mutually connected together and being connected by tie links with the units of adjacent series.

Each unit comprises a pair of wire shanks 5 which are twisted together at 6 adjacent one end to divide the shanks into pairs of relatively long and short sections, the corresponding shank sections being slightly d1 vergent. The short shank sections are terminally bent to form eye loops 7 lying in a horizontal plane, and the longer sections of the shanks are terminally bent to form eye-loops 8 lying in a vertical plane and interlocked with the eye-loops 7 of the next unit whereby a pair of direct longitudinal connections is afforded in each longitudinal series of units to provide a maximum strength particularly for heavy load conditlons. The longitudinal series of units are transversely connected by the links 9 terminally bent to form eye-loops l0 interlocking w1th the horizontal eye-loops 7 of the shanks, to complete the fabric.

These tie links 9 correspond to the laterally connecting arms of the fabric units of my said co-pending application with respect to providing for a transverse resilient flexure of the shank sections to take up sag, but they do not alford the resilient opposition to relative longitudinal movement of transversely adjacent units in the manner afforded by said connecting arms, which are integral with their adjacent unit portions. The eyes 7, 8 and 10 are sufliciently large to permit relative sliding movement in curved lines, and by their size and number, a considerable general resilient yielding is procured under load conditions, in addition to the yielding procured by fiexure of the shank portions.

I claim:

1. A wire fabric unit formed of a pair of longitudinally extending shanks twisted together intermediately -of their ends, the ends of said shanks being at a substantial distance from the twisted portions, and free for transverse resilient flexure of the shank sections, and attaching means for adjacent units at the ends of said shanks.

2. A wire fabricformed of series of units each comprising a pair of separate shanks extending longitudinally of the fabric and twisted together intermediately of their ends, the ends of the unit, each comprising a pair of unconnected shank ends terminatlines and each of said shanks terminating at each end of the unit in a resilient attaching eye.

4. A wire fabric unit comprising a pair 5 of longitudinally extending resilient shanks twisted together adjacent one end of the unit at a suflicient distance from both ends of the unit to allow comparatively free lateral separation, those portions of the shanks 10 between the said twist and the ends of the units being relatively free and divergent, and means for connecting the ends of the shanks with adjacent side and end units.

In testimony whereof I afiix my signature in the presence of two witnesses.

WILBER J. PINE.
